.WILLIAM D. DREISKE, OF CHICAGO, ILLINOIS.

COMBINED WINDOW LOCK AND ADJUSTER.

Specification of Letters Patent.

Application filed October 1913. Serial No. 796,201.

To all whom it may concern:

Be it known that I, WILLIAM D. DREIsKE, a citizen of the United Statesof America, and resident of Chicago, Cook county, Illinois, haveinvented a certain new and use ful Improvement in Combined Window Locksand Adjusters, of which the following is a specification.

My invention relates to casement windows, doors, etc., having devicesfor holding the same in either open or closed position.

Generally stated, the object of my invention is to provide a novel andsatisfactory device or fixture for this purpose.

A special object is to provide a locking device of this kind which willnot only hold the window in open or closed position, but

which will also lock the sash at both ends thereof, as at top and bottomof a casement window, and to thereby provide a combined window lock andadjusting device. In this way, and by employing a single mechanismhaving both of these functions, I obviate the necessity for more thanone fixture for each window, as in this way, it will be seen, thelocking of the bottom of the swinging sash of a casement window servesalso to lock the top thereof, thus rendering a separate lockingoperation unnecessary.

It is also an object to provide certain-details and features ofconstruction tending to increase the generalefliciency of a casementwindow fixture, or combined locking and adjusting device, of thisparticular character.

To these and otheruseful ends, my invention consists in mattershereinafter set forth and claimed.

In the accompanying drawingsFigure 1 is an inside elevation of acasement window having a combined locking and adjusting device embodyingthe principles of my invention. Fig. 2 is a vertical section on line 22in Fig. 1. Fig. 3 is a horizontal section on line 33 in Fig. 1, showingthe window open. Fig. 4c is a similar view,

showing the window only slightly open. llg. 5 is a perspective of thehook shaped end portion of the handle by which the mechanism isoperated, and by which the swinging sash is held in either open orclosed position. Figs. 6, 7, 8, 9 and 10 are views similar to Figs. 1,2, 3, A and 5, respectively, showing another form of my invention.

As thus illustrated, and referring to Figs. 1 to 5 inclusive, the windowframe A may Patented July 28, 1914.

be of any suitable construction. The sash B is hinged at b to swingoutward. A vertically disposed rod C is mounted in bearings c and 0adjacent the free side of the sash, and is formed with upper and lowerarms 0 and 0 the latter being extended to form a handle 0 for operatingthe mechanism. Upper and lower pins D and E are mounted on the windowframe A, adjacent the corners of the sash, and in position to engage thearms 0 and 0 when the window is closed and the handle'swung toward thesash. This draws the sash tightly to the frame, and the hook portion 0is then sprung upward and behind the pin F on the window sill.Preferably the handle 0 is bent upwardly to pass over the pin E inopening the window. To hold the window open the eye 0 of the handle isengaged with the pin E, as shown in Fig. 3. But to hold the window onlyslightly open, the said eye is engaged with the pin F, as shown in Fig.

a. Thus the locking of the bottom of the window serves also to lock thetop thereof. In addition the handle of the mechanism is operative tohold the window open, and to adjust the sash to different positions.

In Figs. 6 to 10 the construction involves a vertical rod G on the frameH, having upper and lower arms 9 and 9 disposed adjacent the corners ofthe sash I, the rod being mounted in bearings and g secured to saidframe. In this case, however, the sash swings inward, instead ofoutward, and the handle 9 engages a pin or other element g on the sash,when the window is closed. In this position the arms 9 and g engage theplates g and g to crowd the sash tightly into position to close thewindow. When the window is open, the handle eye g is engaged with eitherof the pins 9* or 9 which latter are secured to the outside of the sash.Thus the sash is held in either partially or fully opened position.

In each form of my invention the window is locked at top and bottom byone and the same operation. The handle not only locks the window sash ineither open or closed position, but also serves to operate the upperlocking device. Thus only one fixture or mechanism is necessary for eachsash.

In both forms of my invention, it will be seen, the locking arms, andalso the handle, are integral with the rod. As shown, the rod is simplybent into the desired shape,

and thus the securing together of separate partsis avoided. Obviously,however, the said locking arms and handle can be formed or provided inany suitable manner.

In each form of my invention the rod s of elastic material, such as hardbrass or steel, whereby the handle may be sprung into position to holdthe sash in closed position, without permanently bending the same. Thusthe handle and the rod are under tension when the window is locked,

WVhat I claim as my invention is 1. A casement window provided with aswinging sash, and mechanism for holding the window sash in either openor closed position, comprising a rod mounted to rotate on the window,provided with looking arms disposed adjacent the corners of the sash,one of said arms being extended to form a handle, said handle havingengagement with the window to lock the sash in closed position, and tohold the window open.

2. A casement window provided with a swinging sash, and mechanism forholding the window sash in either open or closed position, comprising arod mounted to rotate on the window, provided with looking arms disposedadjacent the corners of the sash, one of said arms being extended toform a handle, said handle having engagement with the window to lock thesash in closed position, and to hold the window open, said arms havinglocking engagement with the window, to firmly close the sash, and saidhandle being movable toward the sash to close and lock the same.

8. A casement window provided with a swinging sash, and mechanism forholding the window sash in either open or closed position, comprising arod mounted to rotate on the window, provided with looking arms disposedadjacent the corners of the sash, one of said arms being extended toform a handle, said handle having engagethe means of ment with thewindow to lock the sash in closed position, and hold the window open,the said rod extending parallel with the free edge of the sash, bearingsfor said rod, disposed between said arms, and a plurality of devices onthe window, serving to provide said engagement with the handle.

4:. A casement window provided with a swinging sash, and mechanism forholding the wine ow sash in either open or closed position, comprising arod mounted to 1'0- tate on the window, provided with locking armsdisposed adjacent the corners of the sash, one of said arms beingextended to form a handle, said handle having engagement with the windowto lock the sash in closed position, and to hold the window open, thesaid rod extending up and down, and said handle being movable in ahorizontally disposed plane at the bottom of the window.

5. A casement window provided with a swinging sash, and mechanism forholding the window sash in either open or closed position, comprising arod mounted to rotate on the window, provided with looking arms disposedadjacent the corners of the sash, one of said arms being extended toform a handle, said handle having engagement with the window to lock thesash in closed position, and to hold the window open, said handle havinga hook with an eye in the end portion thereof, and means on the windowfor engaging the said hook, adapted to enter said eye.
